Paul McCartney and his wife, Heather Mills, want you to know a secret – they’re going to have a baby.

The former Beatle, 60, and his second wife, Heather, 35, who tied the knot last June, announced yesterday that they’re expecting a little one later this year.

“We are delighted with this happy news,” the couple said in a statement.

It will be the first child for Mills, a former model who lost her left leg below the knee in an accident 10 years ago, and the fifth for her husband.

Sir Paul has three children from his 29-year marriage to Linda McCartney, who died of cancer in 1998, and he also adopted her daughter from an earlier marriage.

Yesterday’s joyous announcement came just three months after Mills, who longed for a baby, confided during a talk show chat on British television that she might never be able to conceive.

Mills, who was married briefly in 1989, said she had cancer of the uterus and two ectopic pregnancies, and because of her medical history, all the rumors that she and McCartney were expecting were “really hurtful.”

“The chances of me getting pregnant are about that much,” she said, holding up her thumb and finger an inch apart during the February TV interview.

“And I’m sure for any woman out there, it’s hard enough when your family keeps saying, ‘When are you going to have a baby, then?’ Never mind the whole world keeps saying, ‘Oh, she’s pregnant this week.’ “

Earlier this month, Mills fired back after her ex-husband and former sister-in-law portrayed her as a gold digger on a British TV documentary. Mills went on TV herself and declared, “I’d be happy living with Paul in a shed.”
